U.S. Army Lieutenant Dan Choi, who is being discharged under the military’s anti-gay “Don’t Ask, Don’t Tell” policy, will be a celebrity grand marshal in the San Francisco LGBT Pride Parade Sunday, June 28.

Brendan Behan, deputy executive director of the San Francisco LGBT Pride Celebration Committee, confirmed to the Bay Area Reporter that Choi will be riding in the parade. Behan said that Choi will be part of the Knights Out contingent. The group of West Point alumni recently came out as gay. Choi came out on national television in March, knowing the move could result in discharge proceedings being lodged against him.

Choi is one of two known gay service members who are being discharged since President Obama took office. The other, Army officer Sandy Tsao, recently wrote to the president, asking him to keep his campaign promise to repeal the military ban. Tsao did receive a handwritten note from the president, which indicated he intended to fulfill his promise to end DADT, but she was set to be discharged this week.

DADT prohibits lesbian and gay service members from serving openly in the armed forces.
